Palma - Pros & Cons
Pros
- ✓Clear focus on MCP governance instead of generic agent hype
- ✓Useful separation of concerns between MCP builders and agent builders
- ✓Strong enterprise story around access control, observability, and cost monitoring
- ✓Likely good fit for organizations standardizing AI access to internal systems
Cons
- ✗No public pricing, so evaluation starts with a sales conversation
- ✗Probably overkill for small teams running only a few lightweight automations
- ✗Specialized around MCP, which limits value if your stack is not using MCP-based tooling
- ✗Public customer evidence and independent reviews are still fairly limited
